In the angiograph of the animal experimental,the DSA image quality can be improved and satisfactory effect can be acquired through selecting the parameter of the DSA and controlling the move and respiration of the animal using the methods of medication and physics.

动物实验的血管造影中，选择适当的血管造影机参数，利用药物和物理方法控制动物的移动和呼吸，可以提高数字减影血管造影图像的质量，使动物实验达到满意效果。

Many devices have been applied to the diagnosis of it, such as digital subtraction angiography, color doppler ultrasound, magnetic resonance angiograph, computed tomography angiography and personal vascular laboratory.

其诊断方法很多，包括动脉造影、彩色超声多普勒、核磁共振血管造影、计算机断层血管造影和多功能周围血管检查等。

METHODS 80 eyes of 47 patients with glaucoma (31 eyes of 18 patients with POAG , 27 eyes of 14 patients with NTG and 22 eyes of 15 patients with CACG ) and 44 normal eyes of 39 control subjects were tested by simultaneous ICGA and fluorescein angiography with Heidelberg retina angiograph. The occurrence and extent of peripapillary atrophy and indocyanine green angiographic anormalies of optic disk were compared between glaucoma and control group, and among the three types of glaucoma as well.

应用Heidelberg共焦激光扫描眼底血管造影仪(Heidelberg retina angiograph，HRA)，对青光眼患者47例80只眼(POAG 18例31只眼；NTG 14例27只眼；CACG 15例22只眼)及正常对照组44例44只眼行吲哚青绿眼底血管造影(indocyanine green angiography，ICGA)和荧光素眼底血管造影(fundus fluorescein angiography，FFA)同步检查，比较青光眼与对照组及青光眼各组间视盘旁萎缩(peripapillary atrophy，PPA)以及视盘ICGA表现的差异。

Nine patients were female and one male (ages 31-77, average 52 years). Six patients presented parenchymal vascular lesions (1 angiosarcoma, 1 atypical hemangioma, 3 perilobular hemangiomas, 1 cavernous hemangioma) measuring 0.5-6 cm in the greatest diameter. Two lesions were accidental findings in lumpectomy specimens excised for fibrocystic disease with microcalcifications. Four patients presented non-parenchymal vascular lesions: three cavermous hemangiomas and one angiolipoma measuring 1-6 cm in diameter.

女性9例，男性1例（年龄31-77岁，平均52岁）。6例表现为实质血管性病变（血管肉瘤1例，不典型血管瘤1例，小叶周围血管瘤3例，海绵状血管瘤1例），大小0.5-6cm.2例因乳腺纤维囊型病变伴微钙化在切除的标本上偶然发现。4例呈非实质性的血管病变，其中海绵状血管瘤3例（1例为男性），1例为血管脂肪瘤，最大直径为1.6cm。

In 14 patients with angiogenic tumors of the soft tissue ( 13 benign tumors and 1 malignant tumor) were analyzed. Results Benign hemangiomas included cavernous (n=7), intramuscular (n=2), mixed (n=1), racemosum (n=1), glomus (n=1) and angiomatosis (n=1). The vascular component within the tumor displayed iso-intensity on T1WI relative to the skeletal muscle, and hyper-intensity on T2WI. One case of hemangiopericytoma showed slightly low signal on T1WI and slightly high signal on T2WI.

结果 13例良性肿瘤中，海绵状血管瘤7例，肌肉内血管瘤2例，混合型血管瘤、蔓状血管瘤、血管球瘤、血管瘤病各1例，瘤血管成分在T1WI上呈等信号，T2WI上呈高信号，肿瘤有不等量的纤维组织和脂肪组织；血管外皮细胞瘤1例，T1WI上呈略低信号，T2WI上呈略高信号。

Methods One hundred patients (30 cases of uncertained cerebral angiopathy, 4 cases after embolization of angiodysplasia, 19 cases of cerebral trauma, 30 cases of cerebral tumour,17 cases of other diseases) underwent CT cerebral angiography.

10 0例病人(包括 3 0例疑颅内血管病变，4例血管畸形栓塞术后，19例脑外伤，3 0例脑肿瘤，其他 17例)进行颅脑CT血管造影检查，团注 2 。5～ 3ml/s ，延迟 17～ 2 0s ，凡脑肿瘤者 1～ 1.5min后再进行一次扫描。

Cerebral amyloid angiopathy, defined as deposition of amyloid in the walls of brain vessels, is belived to be a common cause of intracerebral hemorrhage in the elderly.

大脑类淀粉血管病变是类淀粉沉积於大脑血管壁所引起的血管病变，常见於老年人，亦是引起庙颅内出血的重要原因之一。

BACKGROUND: Great saphenous vein is the most common vascular material in coronary artery bypass grafting, however, the graft neointimal hyperplasia and subsequent atherosclerosis result in angiostegnosis, which affect the long-term efficacy.

摘要背景：大隐静脉是冠状动脉旁路移植术最常用的血管材料，但移植血管新生内膜增生和随后发生的粥样硬化所致的移植血管狭窄严重影响远期疗效。

Objective To observe the effects of angiosteosis on the tension of thoracic aortic ring in rats in vitro and its mechanism.

目的：在大鼠血管钙化模型上，观察血管钙化对血管张力的直接影响，并探讨其作用机制。

The histopathological results reveals that alendronate can obvious decrease the area of angiosteosis which inducted by VitD3, as well as lower the contents of calcium in blood vessel and total cholesterol.
